Abstract:
A pneumatic tire has a plurality of recesses provided on the surface of each figures of a first indication portion. The recesses are provided so as to extend in the tire circumferential direction and are aligned side by side with each other in a direction crossing the extending direction. One end side and the other end side in the width direction of each recess are formed by curved surfaces of which a center of curvature is disposed at the outside in the tire width direction. Therefore, gradation of brightness occurs on the curved surface on the each recess. The gradation on the each recess changes depending on the viewing direction or the lighting direction. Therefore, each figure in the first indication portion looks three-dimensionally and can become more conspicuous than the other portions of a side wall.
